The radioactive isotope phosphorus-32 is often used in biochemical research. Its half-life is 14.28 days and it decays by beta emission. If the original sample were 118 mg of K3^32PO4, what amount of P-32 remains after 27.6 d? What percentage of the radioactive isotope has undergone decay? Amount = mg Percentage = %
